Processing method of steel bar cage

Abstract

The invention discloses a processing method of a steel bar cage, which comprises the steps of main bar positioning, wire rod straightening, stirrup winding, carbon-dioxide arc welding, integral forming and numerical control operation. A main bar of the steel bar cage manually penetrates through a corresponding template round hole of a fixed rotary disk into a corresponding hole of a movable rotary disk for fixing; the end of a stirrup is welded on the main bar and then wound on the main bar via rotation of the fixed rotary disk and the movable rotary disk; welding is performed; and then the steel bar cage is formed. The prepared steel bar cage is uniform in spacing and high in accuracy; mechanical rotation, bar coiling and main bar winding are tight; and forming is performed and then an internal reinforcing rib is adopted, so that the concentricity of the steel bar cage is ensured.

Description

technical field [0001] The invention relates to a steel cage processing method. Background technique [0002] At present, in the construction process of building bridges, it is necessary to use circular or square cast-in-place piles as the foundation, and a reinforcement cage must be installed inside the cast-in-situ pile. The traditional method of making reinforcement cages is usually the stirrup forming method. The disadvantage is that the machining accuracy of the steel cage is not high, often the main steel bars at the ends of the steel cage are not in the same section, the spacing of the main steel bars is difficult to maintain uniformity, and the main steel bars are difficult to achieve straightness. More operators, high labor intensity and low production efficiency. Contents of the invention [0003] Aiming at the above-mentioned technical problems existing in the prior art, the present invention proposes a steel cage processing method, which has high processing sp...
